Cone Beam CT of Trauma of Small Bones and Joints

Abstract

Evaluation of trauma of small bones or joints is traditionally done by conventional radiographs (CRs). Although multidetector computed tomography (MDCT) has a better sensitivity than CR in fracture detection and evaluation of complex fractures, high doses of radiation prevent systematic use of MDCT in fracture evaluation. Cone beam computed tomography (CBCT) combines a high spatial resolution and relatively low radiation dose and is therefore a very valuable technique to evaluate trauma of small bones and joints in patients with negative or doubtful radiographs and a high clinical suspicion for fractures or when complex fractures are suspected. CBCT may also be useful for the evaluation of chronic trauma or follow-up of fractures.
